Container use state determining device

Abstract

A container use state determining device includes a signal input unit that receives image data generated by photographing at least one container; and a controller that determines a use state of the at least one container photographed from the image data and makes a display device display information indicating the use state based on a determination result.

What is claimed is: 
     
         1 . A container use state determining device comprising:
 a signal input unit that receives image data generated by photographing at least one container; and   a controller that determines a use state of the at least one container photographed from the image data and makes a display device display information indicating the use state based on a determination result.   
     
     
         2 . The container use state determining device of  claim 1 , further comprising a camera that photographs the at least one container and generates the image data. 
     
     
         3 . The container use state determining device of  claim 1 , further comprising the display device. 
     
     
         4 . The container use state determining device of  claim 3 , wherein the display device is a projector that projects information indicating the use state to a door of the at least one container. 
     
     
         5 . The container use state determining device of  claim 3 ,
 wherein the signal input unit receives the image data photographed by a plurality of cameras,   wherein the controller determines the use state of the at least one container based on the image data, and   wherein the display device displays information indicating the use state.   
     
     
         6 . The container use state determining device of  claim 3 , wherein the display device displays information indicating a container with a given amount or more of empty space. 
     
     
         7 . The container use state determining device of  claim 6 , wherein the display device displays information indicating the container with an empty space in a temporally changing manner. 
     
     
         8 . The container use state determining device of  claim 7 , wherein the display device displays information indicating the container with an empty space in a cyclicly changing manner. 
     
     
         9 . The container use state determining device of  claim 7 , wherein the display device displays information indicating the container with an empty space in an order according to a distance from the display device to the container with an empty space. 
     
     
         10 . The container use state determining device of  claim 3 , wherein the display device displays the image data photographed by a plurality of cameras on one screen. 
     
     
         11 . The container use state determining device of  claim 1 , wherein information indicating the use state includes at least one of a photographed image, a text, a mark, and a graphic image.
